Recover individual tracking points in AE

hello everyone
i’ve tracked a mouth in mocha ae v2.2.1 cs5 and i’d like to recover all the points of the spline mask as many individual tracking points or nulls in AE, is it possible to do so ?
Maybe i have to switch to mocha pro ?
The main purpose is to control lights position.
So far, i’ve been able to paste the mocha mask or to recover a layer effects in AE that give me a matte.

Within AE, I don’t know if i can recover/convert individual mask points into as many different null layers, that would be another solution in that matter.

thanx for the reply ross

the point is that i’ve tried to use the surface, but it gives me unexpected results, in fact the surface is not following properly my tracking spline of the mouth, at certain frames it jumps oddly to other positions and deforms itself widely, in fact approx each time the mouth opens

i really don’t understand why, maybe it’s because i did not select “shear” and “perspective” before tracking the mouth, although this is a fixed close-up shot of a mouth singing and the camera was on a tripod so was not moving at all

i’ve just done a new test with shear and perspective selected, and the results are the same

hello Mary
yeaaah !.. so funny it’s you who are responding my post today because i just discover you for the first time yesterday as i was watching the nab video of yours
don’t want to be rude in any way, but can i tell you that you made me smile because you are such a speed girl, and that is really rare
but i really like it, as i am myself a very speed temper guy :wink:
you make mocha cristal clear as you talks and shows its intricacies, few people got this rare talent to be so precise and didactic
and you communicate a real nice and warm feeling, that’s really noticeable and pleasant :wink:
beside i’ve bookmarked the vid to pay more attention to it during my spare time
all the more i saw on this nab vid that you definitely are a mocha specialist, so i take your answer as precious pieces of advice
thanx for these enlightments, i already undestand much better how mocha works and will for sure undestand a whole lot more better how mocha thinks with the link provided
i am going to watch it very carefully
sorry for my poor english, i am from Paris-france
cheers & keep up’

If your corner pins are jumping around, it means you don’t have a very solid track. Turn your grid and surface tool on in mocha, whatever the surface and grid are doing is that your track is doing, not your shape. The shape is a child of the track and follows what the track is doing. Also make sure you paste your data in on the first frame, and that you align your surface and paste the corner pin data on precomps that are the exact size of your clip in mocha.

Do you get what I mean? If you have any questions, let me know. But you may want to take a minute to watch “how mocha thinks”, as that will breakdown some of the hows and whys of what our tracker is doing and what the shapes actually are. http://www.imagineersystems.com/videos/how-mocha-thinks/

If you still get poor results, there may be some AE scripts floating around in the internet aether that can help you, but I’d rather find you a reliable, in-software solution for this within the mocha to AE workflow.

Hey man,
Thanks, I am glad you like the product and the demos. I appreciate the compliment. Have a great day and let me know if you hit any snags.

There is not an automatic way to translate the shape points to tracking coordinates, but you could do this in a couple different ways.
In mocha AE CS5, you could duplicate your layer a few times and display the surface.
The blue surface represents tracking data that can be exported to AE as corner pin OR transform data. (via export track in mocha). So you could position the corners to align with 4 points on the shape, export as corner pin to AE. Then use an expression to drive or paste each corner’s x,y data to nulls.
Or if you upgrade to mocha AE v3 or mocha Pro v3, you can use the new camera solve and then export surfaces directly out as AE nulls in 3D space. This video covers this workflow: http://www.imagineersystems.com/videos/mocha-v3-tutorial-camera-solving-for-moving-objects/view
